Development
The first prototype of the Type 90-2 Reconnaissance Seaplane, or E4N1, flew in 1930.[1] This was fitted with twin floats and had no cowling for the engine. This prototype was rejected.
The type was completely redesigned as the Type 90-2-2 or E4N2, with a single main-float and twin, wing-mounted outriggers and introduced a cowled engine. This entered production for the Navy in 1931.
A landplane version of the Type 90-2-2 was developed as the E4N2-C with a tailwheel undercarriage
Operational history
The E4N2 was employed as a shipboard spotter aircraft launched by catapult.
In 1933, nine E4N2-C airframes were converted to P1 mail planes. Single-seat landplanes with an enclosed cockpit, these were employed on night-mail services between the Japanese Home Islands.
